Abstract
Cemented versus screw-retained implant crowns effects on peri-implant bone stability remain controversial despite widespread clinical use. Therefore, it is of interest to compare 38 cemented and 38 screw-retained single-implant crowns in posterior sites across 68 patients over 24 months. Screw-retained crowns showed significantly lower mean marginal bone loss (0.68 ± 0.29 mm vs. 1.12 ± 0.34 mm, p<0.001) at 24 months. Excess cement occurred in 34% of cemented cases, strongly correlating with bone loss (r=0.71, p<0.001). Screw retention demonstrates superior bone preservation and reduced biological complications, advancing evidence-based single-implant crown selection.
